Negative Dysphotopsia with Crystalens HD

I had IOL HD500 implant on 24th of March of my left eye. It appeared to be successful, but no I see a very disturbing arch on the left side (dark shadow towards the ear). I contacted my Dr. , he took notes of my complaints, but did not find anything unusual. I contacted Bausch & Lomb. According to them they have never heard about this phenomenon. Controversy to other reports, the dark arch disappears when the pupil is diluted.

I get my right eye don e tomorrow (same lens with same specification). I am now afraid that the same may occure with my right eye.

What are my options?

OK, I guess I never should have read this forum. I think I do have some of the symptoms of Negative Dysphotopsia on my right eye Crystalens HD. Up until today I didn't notice too much flickering on the side of my eye. But trying to read the paper for the first time this morning was very difficult with the flickering on the right side of my right eye.

It almost seems like my eye wants to go back and forth from the negative mode. I don't get it while reading a computer screen. When I was reading the paper I was next to a window getting lots of natural light. My reading ability/acuity is pretty good.

I think the light aberration that I get at night is also causing daytime acuity problems. But, I'm trying not to get too far out in front of my horse.

Looking at my eyes my pupul is not in the center on that eye, its offset. I dont remember the doc ever seeing eye when not dialated.  Maybe its just the way my eye is shaped. I hope not.

My visual acuity is good from 2 feet to 20 feet or so. Maybe will improve over time. The computer looks great through it.  My biggest concern is defanitely the outer edge on ear side. It does not seem to be improving. Funny thing is, day after surgery I don't remember seeing it. Maybe just so amazed at seeing out of that eye again. I asked the doctor about it on week follow up. He didnt know thought possably swelling and recheduled for 30 day appointment. What I can tell you is when he had my eyes dialated And I put my hand to left side where the dark area was (not dialated) I cound see more than one hand. When I decided to go with the crystalens hd I went to Bausch & Lomb for a recommended doctor so I am confident it wasn't a sergical screw up. Maybe I am worried about nothing and the eye will heal.

Hi gixxerjohn,

My first lens gave me instant good view (however, slightly short). I could read the computer straight away. When the Dr. did the second (right) eye, he reduced the optical specs by 0.5 diopters (from 22 first eye to 21.5 for the right eye). Outcome: I can see fairly sharp (left eye from about 15 inch to about 30 feet; right eye from 24 inch to infinity). Although the lenses are slightly different, this is not considered monovision.

I would be a bit nervous not to see reasonably well after the implantation (my Dr. told me it would be instantly). The acuity keeps changing - I guess from constant eye drops and the healing process (I still have a stitch in my right eye). However, if the lens specs have been chosen correctly, I think it should give you instantly reasonable good vision. Only the range of vision should improve over time. I noticed that the accommodation is starting to work as time progresses.

If the specs are wrong, your Dr. may consider exchanging the lens. As fare as I am aware, they can change the lenses within about 4 weeks. After that fibrosis may start (the surrounding tissue will bond with the implant), which makes it more difficult. Even worse, after a YAG.

What is your Dr’s proposing?

I have not had the second eye done yet. The outer shadowing/wiggling is very troublesome to me at this time and vision is not good yet.  Will wait for second eye. Maybe just leave it alone. The eye I had done was the worst of my 2 eyes. If condition corrects and vision improves will have second eye done.

Hi gixxerjohn,

Nothing has changed after one month now. Still dark arches.
My second Christalens has been implanted last week Tuesday. I have the same experience in that eye now. The experts tell me that they have not many cases with Negative Dysphotpsia reported with Christalens.
The “wiggling” is more a reflection on the retina of short movements of your eye (also possibly light flashes from the edge of the lens). I am probably going to live with this phenomenon before I let anyone any invasive actions.

My vision acuity is quite good, both eyes can see about 20/32 (in good light conditions even 20/20).
My night vision is good too, very limited glare (on a scale of 0-10  about 2).

Hence, if nothing dramatically happens, I will just stick with it.

However, I am just curious to what extend others have the same experience (I have some contacts to Bausch & Lomb and will keep them posted as well).

When do you get your second eye done? Let me know whether you experience any changes.
